This makes this practice suitable for flat panels as well as large or 3D objects. A coating system is considered to pass if there is no evidence of water-related failure after a period of time. As the warmer saturated air passes the cooler specimens, atsm is deposited onto the specimens in the form of condensation.

Other tests may also deposit water droplets on the surface but where the source is not from condensation for example, water spray.

Another option is to continue the test until all specimens have failed, and use the time to reach failure as a way to differentiate performance. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This practice differs from other methods where condensation is only formed on the front coating surface, but the back surface is outside the exposure area. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.
